However, good quality orthogonal views are needed to identify and characterise displacement correctly. radial shortening may occur, and if greater than 10 mm, suggests complete disruption of the interosseous membraneA forearm series is usually sufficient for diagnosis and management planning.The TFCC keeps the forearm bones (radius and ulna) stable when the hand grasps or the forearm rotates.It can be demostrated with piano key sign by pressing down ulnar styloid and is positive if it pushes back like a piano key. it cushions and supports the small carpal bones in the wrist. TFCC consists of five parts the articular disc, the superficial and deep (ligamentum Subcruentum) radioulnar fibers, and the two disc-carpal ligaments. The triangular fibrocartilage complex (TFCC) is a cartilage structure located on the small finger side of the wrist.It is the continuation of the deep branch of the radial nerve, after this has crossed the supinator muscle. (volar interosseous nerve) is a branch of the median nerve that supplies the deep muscles on the anterior of the forearm, except the ulnar (medial) half of the flexor digitorum profundus.The posterior interosseous nerve (or dorsal interosseous nerve) is a nerve in the forearm. branch to FDP branch to FPL branch to pronator quadratus. on the basis of direction of radial displacement.Reverse Galeazzi results from fall with hand in supination.Eponymous fracture to galeazzi’s name in adults, nonsurgical treatment of the injury results in persistent or recurrent dislocations of the distal ulna.
